The femoral templates show the neck length and offset for each of the head/ neck combinations (-3.5 to +10.5mm, depending on head diameter). Note: Skirts which may limit range of motion are present on 26mm +7mm, and 26/28/32/36mm +10.5mm femoral heads. WARNING: Higher offsets may increase the potential for ceramic head fracture. Fig. 1
